In 1994, China began making the Beidou Navigation Satellite System (BDS) so that we wouldn’t have to use navigation systems from other countries. It’s a lot safer this way. In 2020, after over 20 years of Chinese scientists’ hard work, Beidou completed its global network (全球网络). That placed China among the group of countries and areas with their own global navigation network, after the US, Russia and the European Union. Beidou does not just show where you are. It’s also the first to let you send texts where there’s no phone signal (信号) or internet. For example, you can use it to send messages to others in a deep mountain. The Beidou system has played a very important role in keeping people from natural disasters, such as earthquakes, storms and so on. The BDS even helps farmers in China by providing information for planting , making farming smarter. The BDS is more than a system. It shows China’s development of science and technology. Now over 120 countries and areas are using it. In the future, there will be certainly more joining it. Wherever you are, Beidou’s there to help you find your way. 1．China decided to make BDS in order to show the development of our space science to the world. 2．China is the fourth one having global navigation systems in the world so far. 3．Beidou is mainly used to help people find the way on the road or in a deep mountain. 4．The popularity of the BDS is rising across the world. 5．It’s not a big deal for Chinese scientists to work out the BDS. B Thirty years ago, China started to build its own navigation satellite system (卫星导航系统), Beidou. It took its name from the Big Dipper stars, which are the guiding light for people around the world. In 1994, China began making the Beidou Navigation Satellite System (BDS) so it wouldn’t have to use navigation systems from other countries. It’s a lot safer this way. In 2020, after over 20 years of hard work, Beidou completed its global network (全球网络). This achievement placed China among the group of countries and regions with their own global navigation network. The US, Russia and the European Union are the other three. Beidou does not just show where you are. It’s also the first to let you send texts where there’s no phone signal (信号) or internet. For example, you can use it to send messages to others in a deep mountain. The Beidou system has played an important role in disaster prevention and response (防灾救灾). The BDS even helps farmers in China by providing precise (精确的) information for planting, making farming smarter. The BDS is more than a system. It shows China’s power in science and technology.

Farmers just sit by the fields and watch the tractors (拖拉机) work. The BeiDou Satellite Navigation System (BDS，北斗卫星导航系统) helps them plant. With the help of BDS, farmers can complete the planting process in a very short time. Modern technology in planting has brought big changes to Wuxuan, one of the big planting areas in Guangxi.“The BeiDou Satellite Navigation System is really amazing. It helps us plant sugarcane in straight lines, and the distance between each row is just right. This way, the sugarcane can get more sunlight and grow better,” said Wu Qihui, an experienced farmer in Wuxuan. He also started a group to help other farmers. Lu Ruwen, a farmer who has been planting sugarcane for more than ten years, joined the group in 2020. Here, he can learn how to use modern technology. “In the past, it took me a week to plant 20 mu of farmland, but now I can finish all the work in just one day,” said Lu Ruwen. He also mentioned that the machines from the group made planting sugarcane much easier and saved him more than 100 yuan per mu. Besides good machines, high-quality sugarcane seeds are also crucial.

It also marks the end of the country’s dependence on America for an important service: location data. GPS was the earliest network to provide global location data. The system is owned by America’s government, which means American officials could decide to turn off or downgrade the signals coming from GPS satellites. The main purpose of building BDS is to give China full control over a navigation system. Work on BDS began in the 1990s and included three phases（阶段）. The first phase was about building the BeiDou-1 system, which started in 1994 and in 2000 provided positioning（定位）, short message telecommunication and timing services in China. The second phase—the BeiDou-2 system, which started in 2004, was completed in 2012. The BeiDou-2 ground system not only serves China but also provides users in the Asia-Pacific region with more than ten satellites and offered services above. The third phase involved the development of the BeiDou-3 system, which started in 2009 and was completed in June, 2020. As one of the IGE members, China is always cooperating with foreign countries and use BDS to serve global users with high performance and high quality in scientific research. BeiDou’s satellites are more advanced（先进的）than those of GPS. In the Asia-Pacific region, BeiDou claims a 10-cm accuracy, compared with 30 cm positioning without doing wrong offered by GPS. America began upgrading its system in 1997 but it may take another 15 years to finish the project. 24．Which of the following name is different from the other three according to the passage? A．BDS. B．GPS. C．Galileo. D．Russia. 25．What’s the importance of the successful launch of BDS? A．It means BDS will be the earliest network to provide global location data. B．It means BDS will be the fourth network to provide global location data. C．It means China can fully take charge of a global navigation satellite system. D．It means we can stop American officials from turning off the satellites signals. 26．What does the underlined word “accuracy” mean in the last paragraph? A．Correct timing. B．Correct positioning. C．Wrong messages. D．Right orders. 27．What can we infer from the passage? A．The completion of BeiDou network puts China ahead technologically. B．It may take the USA more than 30 years to complete the upgrade of GPS. C．America’s GPS is more advanced than BeiDou in the Asia-Pacific region. D．There will be more countries depending on BeiDou system in the future. G How many of us could go a week without(不用)our phones? I can’t even remember the last time I went a day without the Internet. Technology(科技)makes our life easier. However, we have to face the fact: Technology makes us lazy. In the past, when we wanted to do something relaxing, we got dressed and drove to the movies or went out to have fun with friends. Now we don’t need to go out. ▲ We just sit on the sofa and turn on the computer. Then we can have much fun. We find the answer to anything with Baidu. When we have a problem, we usually try to find out the answer online. Many of us don’t try to read books or ask for help to work out the problem. I get the feeling that we’re getting closer and closer to the day when people won’t even be able to read paper maps. Many young people have no idea how to find a place in their own cities without using a BDS. How can we detach from too much technology? Using technology becomes one of our habits and we can never stop using it. What we can do is to start doing things more without technology. We have to learn how to enjoy our free time without it. Although it’s not easy, we can start from small things. For example, turn off phones and computers from time to time and check(检查)e-mails and QQ or We-chat only once or twice a day. We can also do something interesting without using technology, like playing sports and walking a dog. 28．Which can be put into ▲ A．We can’t stop using technology. B．We don’t need to leave the house for fun. C．People enjoyed outdoor sports before. D．Young people would like to have fun at home. 29．Many young people ________ to find a place. A．use a BDS B．read paper maps C．draw a road map D．ask others for help 30．The underlined words have the closest meaning to ________. A．hear from B．learn from C．break away from D．be different from 31．What’s the passage mainly about? A．Technology is everywhere in our life. B．It’s easier for us to use technology. C．We are too lazy to use technology. D．Too much technology is not good for us. 二、任务型阅读 A 阅读与回答。 China’s Bei Dou Satellite Navigation System (BDS) (卫星导航系统) is thought as the world level. This makes it one of four global (全球的) satellite navigation systems, together with the United States’ GPS, Russia’s GLONASS and the European Union’s Galileo. China started to develop the BDS in 1994. The system came into use in 2000. After 12 years of work, it began working for the Asia-Pacific part. In 2020, with the global use of BDS-3, China has improved the system to provide users with more correct positioning (定位) services, making it an important tool for more industries (行业), including transportation, agriculture, and surveying. Now, with 59 satellites in its network, the BDS has served more than 1.5 billion users across the world. Most mobile apps providing maps, navigation and shopping services in China already support the BDS. China’s satellite navigation industry is growing fast. Its value (价值) reached more than 500 billion yuan in 2022. That number may double by 2025. In the first half year of 2023, there were about 13.4 million new BDS devices (设备). Nearly 60% were used in transport systems. The rest were used in communication and agriculture. As BDS gets more popular, it is expected to play an important role in global navigation and positioning services. 32．How many global satellite navigation systems are there now? 33．When did China start to develop the BDS? 34．Why has China improved the system? 35．Where were 60% of the new BDS devices used? 36．As a teenager, how do you feel after reading the passage? B 阅读短文,根据短文内容回答问题。 In ancient times, people depended on stars to guide them on a clear night. Today, we have navigational systems (导航系统) to help us find our way. The recent one is the Beidou Navigation Satellite System (BDS). The Chinese engineers built the BDS independently. With the launch of the last satellite from the Xichang Satellite Launch Center on June 23, 2021, the global (全球的) network of 59 satellites has been completed. On July 31 of the same year, Beidou started providing services to the world. It’s difficult to imagine. BDS When you unlock one of Hellobike’s bicycles, you are using the BDS. Users can also find shared bikes more easily thanks to Beidou’s positioning service. However, the BDS doesn’t just work one way. As the country’s largest space-based system and one of four global navigation networks, Beidou has a two-way communication system, including its ability to receive messages sent by people from areas with poor communication signals. Obviously, it isn’t designed for users to chat online. Instead, it plays a role when disasters happen and communications are blocked. After the Wenchuan earthquake in 2008, all ground-based communication facilities (设施) were interrupted. Though the first generation of Beidou could only send 120 characters in a single message at that time, communication between affected areas and rescue centers was successful. Now, Beidou can send 1,200 Chinese characters in a single message. As Sun Jiadong, former chief designer of the BDS said, “The application( 应用) of Beidou is only limited by imagination.” 37．What’s the recent navigational system? 38．When did the BDS start providing services to the world? 39．What communication system does BDS have? 40．How many Chinese characters can Beidou send in a single message now? 41．What do you think of the Beidou Navigation Satellite System? Why? 试卷第1页，共3页 试卷第1页，共3页 学科网（北京）股份有限公司 $$ 23北斗卫星导航系统 北斗卫星导航系统 中国自行研制的全球卫星导航系统 北斗卫星导航系统（BeiDou Navigation Satellite System）是中国自行研制的全球卫星导航系统，也是继GPS、GLONASS之后的第三个成熟的卫星导航系统。 其由空间段、地面段和用户段三部分组成，可在全球范围内全天候、全天时为各类用户提供高精度、高可靠定位、导航、授时服务。 2023年12月26日，中国在西昌卫星发射中心成功发射第五十七颗、五十八颗北斗导航卫星 一、阅读理解 A 阅根据短文内容，判断下列句子正误。正确的涂A，错误的涂B。 Thirty years ago, China started to build its own navigation satellite system (卫星导航系统), Beidou.

It also marks the end of the country’s dependence on America for an important service: location data. GPS was the earliest network to provide global location data. The system is owned by America’s government, which means American officials could decide to turn off or downgrade the signals coming from GPS satellites. The main purpose of building BDS is to give China full control over a navigation system. Work on BDS began in the 1990s and included three phases（阶段）. The first phase was about building the BeiDou-1 system, which started in 1994 and in 2000 provided positioning（定位）, short message telecommunication and timing services in China. The second phase—the BeiDou-2 system, which started in 2004, was completed in 2012. The BeiDou-2 ground system not only serves China but also provides users in the Asia-Pacific region with more than ten satellites and offered services above. The third phase involved the development of the BeiDou-3 system, which started in 2009 and was completed in June, 2020. As one of the IGE members, China is always cooperating with foreign countries and use BDS to serve global users with high performance and high quality in scientific research. BeiDou’s satellites are more advanced（先进的）than those of GPS. In the Asia-Pacific region, BeiDou claims a 10-cm accuracy, compared with 30 cm positioning without doing wrong offered by GPS. America began upgrading its system in 1997 but it may take another 15 years to finish the project. 24．Which of the following name is different from the other three according to the passage? A．BDS. B．GPS. C．Galileo. D．Russia. 25．What’s the importance of the successful launch of BDS? A．It means BDS will be the earliest network to provide global location data. B．It means BDS will be the fourth network to provide global location data. C．It means China can fully take charge of a global navigation satellite system. D．It means we can stop American officials from turning off the satellites signals. 26．What does the underlined word “accuracy” mean in the last paragraph? A．Correct timing. B．Correct positioning. C．Wrong messages. D．Right orders. 27．What can we infer from the passage? A．The completion of BeiDou network puts China ahead technologically. B．It may take the USA more than 30 years to complete the upgrade of GPS. C．America’s GPS is more advanced than BeiDou in the Asia-Pacific region. D．There will be more countries depending on BeiDou system in the future. 【答案】24．D 25．C 26．B 27．A 【知识点】说明文、科学技术、科普知识 【导语】本文主要介绍了北斗卫星导航系统的建成和重要作用。 24．细节理解题。根据“operated BeiDou network, one of the four global navigation networks, along with the USA’s GPS, Russia’s GLONASS and the European Union’s Galileo”可知，GPS，BDS，Galileo都是卫星导航系统，D选项Russia是国家名称，故选D。 25．推理判断题。根据“The system is owned by America’s government, which means American officials could decide to turn off or downgrade the signals coming from GPS satellites. The main purpose of building BDS is to give China full control over a navigation system”可知，北斗卫星导航系统的成功发射意味着中国可以完全掌控一个全球卫星导航系统，故选C。 26．词义猜测题。根据“In the Asia-Pacific region, BeiDou claims a 10-cm accuracy, compared with 30 cm positioning without doing wrong offered by GPS”可知，此处是将北斗与GPS的定位准确度相比较，北斗的定位精确度更高，所以accuracy指“正确定位”，故选B。 27．推理判断题。根据“In the Asia-Pacific region, BeiDou claims a 10-cm accuracy, compared with 30 cm positioning without doing wrong offered by GPS”可知，北斗比GPS更先进，在定位精确度上为10厘米，由此可推断，北斗网络的建成使中国在技术上处于领先地位，故选A。 G How many of us could go a week without(不用)our phones? I can’t even remember the last time I went a day without the Internet. Technology(科技)makes our life easier. However, we have to face the fact: Technology makes us lazy. In the past, when we wanted to do something relaxing, we got dressed and drove to the movies or went out to have fun with friends. Now we don’t need to go out. ▲ We just sit on the sofa and turn on the computer. Then we can have much fun. We find the answer to anything with Baidu. When we have a problem, we usually try to find out the answer online. Many of us don’t try to read books or ask for help to work out the problem. I get the feeling that we’re getting closer and closer to the day when people won’t even be able to read paper maps. Many young people have no idea how to find a place in their own cities without using a BDS. How can we detach from too much technology? Using technology becomes one of our habits and we can never stop using it. What we can do is to start doing things more without technology. We have to learn how to enjoy our free time without it. Although it’s not easy, we can start from small things. For example, turn off phones and computers from time to time and check(检查)e-mails and QQ or We-chat only once or twice a day. We can also do something interesting without using technology, like playing sports and walking a dog. 28．Which can be put into ▲ A．We can’t stop using technology.

This makes it one of four global (全球的) satellite navigation systems, together with the United States’ GPS, Russia’s GLONASS and the European Union’s Galileo. China started to develop the BDS in 1994. The system came into use in 2000. After 12 years of work, it began working for the Asia-Pacific part. In 2020, with the global use of BDS-3, China has improved the system to provide users with more correct positioning (定位) services, making it an important tool for more industries (行业), including transportation, agriculture, and surveying. Now, with 59 satellites in its network, the BDS has served more than 1.5 billion users across the world. Most mobile apps providing maps, navigation and shopping services in China already support the BDS. China’s satellite navigation industry is growing fast. Its value (价值) reached more than 500 billion yuan in 2022. That number may double by 2025. In the first half year of 2023, there were about 13.4 million new BDS devices (设备). Nearly 60% were used in transport systems. The rest were used in communication and agriculture. As BDS gets more popular, it is expected to play an important role in global navigation and positioning services. 32．How many global satellite navigation systems are there now? 33．When did China start to develop the BDS? 34．Why has China improved the system? 35．Where were 60% of the new BDS devices used? 36．As a teenager, how do you feel after reading the passage? 【答案】32．Four. 33．In 1994. 34．To provide users with more correct positioning services. 35．In transport systems. 36．Very proud/excited. 【知识点】说明文、科学技术、科普知识 【导语】本文介绍了中国的北斗卫星导航系统（BDS），它是全球四大卫星导航系统之一，已为全球超过15亿用户提供服务，广泛应用于多个行业，并预计未来将在全球导航和定位服务中发挥重要作用。 32．根据“China’s Bei Dou Satellite Navigation System (BDS) (卫星导航系统) is thought as the world level.

B 阅读短文,根据短文内容回答问题。 In ancient times, people depended on stars to guide them on a clear night. Today, we have navigational systems (导航系统) to help us find our way. The recent one is the Beidou Navigation Satellite System (BDS). The Chinese engineers built the BDS independently. With the launch of the last satellite from the Xichang Satellite Launch Center on June 23, 2021, the global (全球的) network of 59 satellites has been completed. On July 31 of the same year, Beidou started providing services to the world. It’s difficult to imagine. BDS When you unlock one of Hellobike’s bicycles, you are using the BDS. Users can also find shared bikes more easily thanks to Beidou’s positioning service. However, the BDS doesn’t just work one way. As the country’s largest space-based system and one of four global navigation networks, Beidou has a two-way communication system, including its ability to receive messages sent by people from areas with poor communication signals. Obviously, it isn’t designed for users to chat online. Instead, it plays a role when disasters happen and communications are blocked. After the Wenchuan earthquake in 2008, all ground-based communication facilities (设施) were interrupted. Though the first generation of Beidou could only send 120 characters in a single message at that time, communication between affected areas and rescue centers was successful. Now, Beidou can send 1,200 Chinese characters in a single message. As Sun Jiadong, former chief designer of the BDS said, “The application( 应用) of Beidou is only limited by imagination.” 37．What’s the recent navigational system? 38．When did the BDS start providing services to the world? 39．What communication system does BDS have? 40．How many Chinese characters can Beidou send in a single message now? 41．What do you think of the Beidou Navigation Satellite System? Why? 【答案】37．The recent one is the Beidou Navigation Satellite System (BDS). 38．On July 31, 2021. 39．Beidou has a two-way communication system. 40．Now, Beidou can send 1,200 Chinese characters in a single message. 41．Beidou Navigation Satellite System is quite useful and helpful. Because it is convenient for people to find their way and find shared bikes more easily. The application of Beidou is only limited by imagination. 【知识点】说明文、信息技术、科普知识 【分析】这是一篇说明文，文章讲述北斗卫星导航系统的应用和各种用途。 37．根据第一段“The recent one is the Beidou Navigation Satellite System (BDS)”可知，现在的导航是北斗卫星导航系统。故填The recent one is the Beidou Navigation Satellite System (BDS). 38．根据第二段“on June 23, 2021, the global network of 59 satellites has been completed.
